| 摘 要： | 用lgM、(lgM)2等分子参数为独立参量,通过回归方法建立数学模型来预测70种单质的标准熵[Sm0/(J.mol-1.K-1)],其回归方程为:Sm0=-5.056 20.704lgM 4.019(lgM)2,R=1.000.其预测结果表明该模型的原理简单,方法实用,结果可靠.

| Abstract: | In this paper,two parameters are used to correlate the standard enthalpy of 70 cations in solid compounds.And the liner regression equation is set up by the least square method: Sm0 =-5.056 20.704lgM 4.019(lgM)2,R = 1.000.The new indices have a higher calculation accuracy.It is concluded that the indices bear good structure selectivity and property relativity.It shows that the method possesses the advantage of easy computation and clear physical significance. |
